Choosing solar installers in London
Start a London solar enquiry with your full address, property type and who owns the roof. A house, a leasehold flat and a shared-roof block need different project briefs. If other owners or a managing agent are involved, establish who can authorise a survey and the proposed works before arranging installation.
London City Hall's rooftop-solar planning page describes work with boroughs on planning policies for existing buildings. Its linked borough-policy research dates from 2022. Use your borough's current advice for a property-specific enquiry; a London-wide policy ambition does not give consent for an individual roof.
Ask installers to show how neighbouring buildings, chimneys and roof structures affect the proposed layout. Request the shading assumptions behind the generation estimate and an explanation of any panels left out of the design. For a shared roof, ask which electricity supply the system would serve and what access would be needed for future maintenance.
Access costs deserve their own line in the quotation. Ask where scaffolding would go, how equipment would reach the roof and whether any permissions for access are excluded from the price. Agree who will coordinate with the freeholder or managing agent where relevant.
Use TopGreenDeals to compare London solar installer profiles and contact a shortlist with the same address and roof information. Review the design, permissions responsibilities and access costs before choosing a contractor.

Frequently asked questions
- Can I arrange solar panels for a London flat?
- First establish who owns or controls the roof and which permissions are needed from the freeholder or other owners. Ask an installer which electricity supply the proposed system would serve and how maintenance access would work.
- How do I compare solar panel installers in London?
- Give each installer the same roof details, postcode and electricity-use information. Compare the proposed layout and generation estimate together with access arrangements, scaffolding, cable routes and aftercare, so each price covers a comparable installation.
- What access details should I ask a London installer to price?
- Request the scaffolding arrangement, equipment delivery route and any permissions needed for access. Ask which items are included and who is responsible for coordinating with a managing agent or other property owners.
